Rainbow Rocks her World

Rainbow finally left the Crystal Empire, having spent a week...helping, the rulers. She was not, however, heading for home, but Canterlot-Celestia had sent her a letter, commending her on her friendliness and helpfulness lately, and asking for some help herself. Rainbow couldn't help but wonder if she meant help, or 'help' like the Crystal Cucks. It hardly mattered, she mused-either way, it was...politics, right? More clout for her!

She leaned back in her seat-imaging Celestia nice and fat with Rainbow's offspring like the rest of their friends. She wondered if Twilight had told her mentor about their mutual pregnancies, and that Twi's was Rainbows. She didn't know if a mare as old-wait no, that's rude. Twilight said to use timeless. As timeless as Celestia was, could she still have children? Discovering that by fucking and impregnating her was so hot...Rainbow used her wings to hide her boner. Dammit, not again...

She now hunched over, wings covering her, grumbling at her horny parts and the rocking and vibrating the train gave those same parts. She couldn't be more relieved when the train finally pulled into Canterlot station, flying off the train and right to the castle. The guards knew her and her friends, so she could just trot right past with nothing more than a nod.

One of the ones in a hall directed her to Celestia, apparently having been waiting for her in her...chambers. Rainbow tried not to look as horny or as lucky as she felt. She strutted along now, both smug and horny, thick girlcock swinging under her. She didn't care if the guards stared-at her size, she had nothing to be ashamed of. And while yes, she did get some envious stares, she got much more interested ones no matter the gender.

She paused out side Celestia's chambers, guards absent here. Even Rainbow had cottoned on to the fact they were for show, being ruled by literal goddesses. Speaking of... she raised a hoof, knocking politely. She heard Celestia sigh.

"Come in,"

She did so, confused now-did she not want to see Rainbow? She opened the door, entering. "Princess," she bowed, Celestia jumping off her bed. "Oh! Rainbow Dash! Apologies-I...well, I expected you to slam the door open, I didn't think you'd knock," she admitted, blush showing easily through pristine white.

She cleared her throat, "Well, I expect you wish to know why I asked you here. I must ask for discretion on your part. I know this is hard, but not impossible for you," she added, looking serious. Rainbow stood up from her bow, "Of course, Princess. I don't think anyone would believe anything I say as more than a brag anyway," she snorted, smirking, the princess chuckling with her.

"Perhaps...but, thank you. Now," she shut the door, "I hear you have been...relieving stress, for friends and my fellow princesses. I..." "You're in season too, right?" "..." the intensifying blush was all the answer she needed, or was getting. "Hey, it's cool, princess! I got mine sated like, two weeks ago. I'm not gonna be mean or anything about a princess getting in season! So like...what foal control do you use?"

Celestia shuffled her hooves, looking away and back. "Ah, gotcha! But I gotta ask, why me?" "Oh! Well, I wanted to have a child...but the nobility, ugh," she rolled her eyes, Rainbow seeing a rare glimpse as Celestia as a pony, not her ruler or goddess. "I...put a lot of thought into this. I...will admit to asking Twilight first...but...she...wants us to bear each others children and asked I wait until yours is here. So I thought...surely, you would be the next to ask-an Element Bearer, to silence the nobles. A good friend, to ease any fears I might have. And, I admit to this too, hearing Twilight sing your praises in bed did sway me a fair amount."

Rainbow nodded, "All pretty good reasons." "Oh. One more thing! I know it's weird, but, I...want to be a normal pony during. Don't worry! It's just a glamour and size spell. I just...want to shed the crown for a night, feel like I have no expectations, from others and myself."

"Princess, I get it. You want to be free for a night, get rid of your stress. It's fine with me! However you want it, or want to do it." She assured the larger mare, rubbing a hoof along the long, elegant front leg in front of her. Celestia nuzzled her. "Thank you...and I am glad, I do want to try something...a bit odd, I suppose?" "Sure. I trust you."

Celestia beamed, stepping back to cast her spells. First, the size-she shrunk slowly to the size of Rainbow, maybe slightly taller. Another spell, the glamour. She kept her coat and mark, losing her horn and shrinking her wings, her hair fading to plain pink. She chirped in a much higher voice, "I wanna be called Sunny!" Rainbow laughed, "Sunny huh? I like it!"

'Sunny' sat on the bed. She picked up two small hoops sitting on it, engraved with runes. "So, the weird sex thing we'll be doing," she blushed to put it so bluntly, "Is portals! See, you put this one on the...insertion, and it comes out this one, to be used like a toy, but with all the added bonuses of real...c-cockflesh," despite her red face and stammering, her sopping wet pussy showed how much she liked being vulgar.

"Huh...well, that's something I've never tried before," Rainbow admitted, taking a portal. She sat on the bed, spreading her legs to show her heavy sheath and long cock. Sunny tried not to stare-so large...even at her alicorn size that would give her a good stretch.

"So I just...put my dick through it?" "No! I mean...yes, but first, can I..." Sunny reached a hoof to Dash's cock. "Oh! Yeah, sure," she grinned, kind of excited at getting another blowjob from a princess, even if she technically wasn't one right now.

Sunny slid off the bed, sitting in front of her, taking the massive rod in her hooves, admiring it before sliding up and down it slowly. She lapped at the shaft, from sheath to tip, swirling her tongue about the head. She suckled on it, looking up at Rainbow with half lidded eyes, before she took it in her mouth. The throbbing fuckstaff got halfway in, and she had to pull back again, blushing. This was harder than she remembered, but it had been some time.

The blush intensified as Rainbow pulled up onto the bed on her back, Rainbow laying next to her, and pulling a hoop over her cock. As promised, it exited from the other one. Sunny picked that one up, nervously licking it. Rainbow moaned in appreciation, disembodied cock twitching.

Feeling encouraged by Rainbow's enjoyment, she put the hoop on the bed so the cock stuck up like a dildo, moving over it to tease the tip with her drooling, hot cunt. "Y-you like this? Being used as my s-sex toy?" she asked, trying to talk dirty without sounding too awkward.

"Hell yeah, pleasure that hot, pretty pussy on my cunt swab, just a cum donor for your breeding and pleasure," Rainbow was much more of a natural at dirty talk. Sunny rubbed her pussy against the flared cock head, panting. "That...that is right, a tool for my breeding!" and pushed down on the cock, spreading her labia wide, popping inside the pussy properly. She had to pause, gasping and wriggling as it stretched her wide.

She bounced on the cock, holding it still with her back hooves on the ring, whimpering and moaning. Rainbow took advantage of this all, coming up behind Sunny and hugging her, hooves rubbing at the other's teats as she lifted the mare enthusiastically on her futacock.

"R-rainbow! I...it-it's too much, I can't-" "Then don't! Let go, let me pleasure you tonight." Sunny cried out, her orgasm splattering the bed and milking RD's cock. She collapsed against Rainbow, who took the ring off her cock. She rolled so Sunny was on her back, Dash on top.

Dash lifted her partner's back legs, pile driving hard through the sopping wet cunt, tight cervix, her flared cocktip filling the space. Sunny whimpered, front legs around Dash's neck. Dash kept thrusting, holding off in the hot, wet confines. She was going to fill Sunny like a balloon when she finally popped. She kept up strong, long strokes, Sunny's hind legs trembling around her.

Sunny came again, gasping in pleasure and exhaustion, the suckling feeling all Dash needed to drop off the edge. She thrust as she came, bloating the other's womb. Each throb of her cock filled the other more and more, until it splattered around the penetration with each thrust. Dash pulled out, using her hooves and wings to get the last spurts over Sunny's body, who half dazed, rubbed it into her fur with satisfaction.

Rainbow layed next to her, pulling her into a spooning hug. "S'it alright if i stay the night?" she asked, yawning. Sunny blushed, but nodded. "S-sure. The spell will wear off by then," "That's fine. It's been you the whole time no matter what you look like," she shrugged, Sunny smiling and closing her eyes. What fun it had been!
